RT Journal Article SR Electronic T1 Clinical Histories Animate Muybridge and Dercum's Original Photographic Study of Neurologic Gait JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 1026 OP 1030 DO 10.1212/WNL.0000000000012879 VO 97 IS 22 A1 Noble, Geoffrey YR 2021 UL http://n.neurology.org/content/97/22/1026.abstract AB In 1885, while working at the University of Pennsylvania, Eadweard Muybridge and Francis Dercum used nascent photographic technology to perform the first-ever motion picture study of neurologic patients. To date, our clinical understanding of the Muybridge-Dercum project has been limited to those clinical details included in a handful of contemporaneous publications by Dercum et al. In this study, recently rediscovered clinical notebooks from the Hospital of the University of Pennsylvania's Dispensary for Nervous Diseases were reviewed and found to contain the original clinical records of 9 of Muybridge and Dercum's photographic subjects. These records add new clinical insights into our understanding of this historic photographic study and revive the zeitgeist of a foundational period in the development of neurology as a medical subspecialty in the United States.
